Title: Driving circuit for switch element
Inventor: SOFUE KENICHI
IPC: H03K17/04
Filed: 1989-10-09
Abstract: PURPOSE:To prevent a delay in rise of a driving current of a switch element and to improve the responsiveness by providing a voltage adjustment means, and setting a DC constant voltage from a DC power supply higher than a voltage inputted in the operation of the said switching element. CONSTITUTION:When a switching transistor(TR) 8 is turned on, no base current Ib flows to a power TR 3 and is turned off. Since an output voltage Vb of a reference voltage circuit 9 reaches a high level, a DC constant voltage Vd of a constant voltage output circuit 11 is adjusted to a high level. On the other hand, just before a TR 3 is again turned on from the said state, the DC constant voltage Vd inputted to a MOSFET 6 is kept to a high level. That is, just after the operation of the power TR 3, the output voltage of the constant voltage output circuit 11 is kept high. Since the rise of the base current Ib is based on a high level, the time reaching the rise steady state is very rapid.

IPC: C04B35/45
Filed: 1988-10-21
Abstract: PURPOSE:To raise the superconducting critical temperature and to increase the volume ratio of high-temperature phase by melting a raw material constituting a Bi-Sr-Ca-Cu-O oxide superconductor under a specific condition and increasing oxygen partial pressure of the system to convert the mixture into a solid phase. CONSTITUTION:A precursor for a superconductor is produced by mixing Bi2O3, SrCO3, CaCO3 and CuO at ratios to get the composition of Bi2Sr2Ca2Cu3Ox, crushing the mixture and heating at 600-900 deg.C for about 10hr. The precursor is completely melted in vacuum or in an inert gas atmosphere within a tempera ture range (820-850 deg.C) in which at least a phase having high critical temperature is stably maintained. The oxygen partial pressure is raised to 0.01-0.05 atm to cross a liquid-phase line and precipitate a solid phase having high critical temperature as an initial crystal. The oxygen partial pressure is further raised to 0.15-1 atm until the composition crosses the solid-phase line to obtain a solid phase. The Bi-Sr-Ca-Cu-O oxide superconductor produced by this process contains >=95vol.% of a phase having high critical temperature (2223 phase).

IPC: F24C3/12
Filed: 1986-11-06
Abstract: PURPOSE:To prevent smoke, fire and flame from generating by bringing the sensing part of a temperature sensor stopping the heat generation into contact with a projection formed at a position higher than the bottom surface of a saucer placed at the bottom part of a grill box, and thus stopping the generation of heat of a heating unit before water within the saucer is evaporated out. CONSTITUTION:When the temperature within a grill box 16 is raised to a predetermined value, a heat sensing part 23a of a temperature switch 23 opening and shutting a circuit of a upper heating unit 18 and lower heating units 19 is provided on the bottom surface of a saucer 21, and is brought into contact with the back surface of a projection 21a located at a position higher than the bottom surface of the saucer 21. Water in the saucer 21 is heated by the rise in the temperature within the grill box and the lower heating units 19, and the temperature of water is raised and water is evaporated. Before water within the saucer 21 is all evaporated, since the projection 21a provided in the saucer 21 is located at the position upper than the bottom surface, water there is evaporated previously and its temperature is raised suddenly. When the heat sensing part 23a brought into contact with the projection 21a reaches a certain temperature, the heat sensing part 23a senses it, and opens the circuit of the upper heating unit 18 and lower heating units 19 to cut off power supply, and does not continue evaporation until water in the saucer is exhausted.
